IVUS-guided stent placement for blocked heart artery using longer guidance
Part of Heart & circulation clinical trials.
This trial compares two ways to place a stent (a small mesh tube) for a completely blocked heart artery: using an IVUS camera inside the artery versus using a standard x-ray approach. It may help people get better heart outcomes by improving how accurately the stent is placed in long-term blockages.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be at least 18 years old and be able to understand and sign consent
- Have symptoms or heart-test evidence that the blocked artery is limiting blood flow, and plan to have a heart procedure (PCI)
- Be willing to accept the study treatments and attend all follow-up visits
- Have a complete blockage (TIMI 0) that has been present about 3 months or longer, and the blockage is long (over 20 mm)
- The blockage must be in the right place for a certain stent size (about 2.25–4.0 mm) and have visible collateral blood flow

Other trials that look related to this one.
This trial studies whether opening a completely blocked heart artery (a CTO) with a procedure and stent helps reduce areas of low blood flow in the heart, compared with the best medicines alone. It uses heart scans to find people likely to benefit and then checks results again at 6 months.
This trial studies whether two ways of threading a device to open a long-term blocked coronary artery are both safe and effective. You may qualify if you have a chronic total blockage and heart-related symptoms, and you can follow the study follow-up plan.
This trial studies a heart procedure that uses a special camera to guide where to place a drug-coated stent in an artery with heavy calcium. It may help improve how well the stent fits and works for people with certain types of coronary artery blockages.
This trial is testing whether a special heart CT scan (coronary CT angiography) can help doctors better understand and treat calcium buildup in your heart arteries. If you have a type of heart disease that might need a stent or other procedure, this study could help decide the best approach.
This trial tests a new imaging and catheter system to treat chronic total blockages in heart arteries. If you still have chest pain or other symptoms despite medical therapy, this study may help open the blockage and improve blood flow.
This trial tests whether opening completely blocked heart arteries with a stent (angioplasty) helps people with heart failure and chest pain or shortness of breath. It aims to see if this procedure improves how well the heart works and reduces symptoms.
